Xcode Command Line Tools - The Xcode Command Line Tools must be installed for the currently installed version of Xcode (see below for installation details).Xcode and iOS SDK - Apple's Xcode and the latest iOS API need to be installed and configured on the developer's computer.

Additionally, the following is required to complete the steps presented: This article assumes that you have some familiarity with Xcode and the Objective-C language and you have read ourĭocumentation. After we've seen how to use a strong delegate, we'll cover how to use weak delegates to perform the same tasks. The sample application will demonstrate how to use a strong delegate for communication between the InfColorPicker API and our C# code.

Finally, we'll create a Xamarin.iOS application that uses the binding.

Next, show how Objective Sharpie can reduce the workload by automatically generating some (but not all) of the necessary API definitions required by the Xamarin.iOS binding.

Then, we'll bind this static library with Xamarin.iOS.

First, we'll create an Objective-C static library using Xcode.

We'll cover all the necessary steps to consume this particular Objective-C API in Xamarin.iOS: The InfColorPicker library provides a reusable view controller that allows the user to select a color based on its HSB representation, making color selection more user-friendly.

This article provides a step-by-step walkthrough of creating a binding project using the open source InfColorPicker Objective-C project as an example, however all information in this guide can be adapted for use with any third-party Objective-C library. Remember, before you start to create a binding, always check the licence provided with the library to ensure that you are free to bind it. In the first and second scenario there will already be a precompiled CocoaTouch Static Library so in this article we will focus on the third scenario. This is just a folder containing the static library, headers and sometimes additional resources with. a extension together with its header(s) (.h files). As a precompiled static library file with.Generally in the iOS ecosystem you can find libraries in 3 flavors: In those situations, you can use a Xamarin.iOS Binding Project to create a C# binding that will allow you to consume the library in your Xamarin.iOS applications. When working on iOS, you might encounter cases where you want to consume a third-party Objective-C library. It covers topics such as compiling a static Objective-C library, binding it, and using the binding in a Xamarin.iOS application. This article provides a hands-on walkthrough of creating a Xamarin.iOS binding for an existing Objective-C library, InfColorPicker. Please take this survey to inform future development efforts. We're currently investigating custom binding usage on the Xamarin platform.
